System Commands

System commands control system functions that are not directly related to output control, measurement, or status functions. Common commands are also used to control system functions.

SYSTem:COMMunicate:RLSTate LOCalREMoteRWLock

SYSTem:COMMunicate:RLSTate?

This command configures the remote/local state of the instrument according to the following settings.

LOCal The instrument is set to front panel control (front panel keys are active). REMote The instrument is set to remote interface control (front panel keys are active).

RWLock The front panel keys are disabled (the instrument can only be controlled via the remote interface).

The remote/local state can also be set by interface commands over the GPIB and some other I/O interfaces. When multiple remote programming interfaces are active, the interface with the most recently changed remote/local state determines the instrument’s remote/local state.

The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMunicate:RLState. At power-on however, the communications setting always returns to LOCal.

SYSTem:COMMunicate:TCPip:CONTrol?

This query returns the control connection port number. This is used to open a control socket connection to the instrument. Refer to chapter 4 under “Using Sockets” for more information.

SYSTem:ERRor?

This query returns the next error number and its corresponding message string from the error queue. The queue is a FIFO (first-in, first-out) buffer that stores errors as they occur. As it is read, each error is removed from the queue. When all errors have been read, the query returns 0, NO ERROR. If more errors are accumulated than the queue can hold, the last error in the queue will be -350, TOO MANY ERRORS (see Appendix C for error codes).

SYSTem:VERSion?

This query returns the SCPI version number to which the instrument complies. The returned value is of the form YYYY.V, where YYYY represents the year and V is the revision number for that year.
